To enable the ADC processor pipeline, the web.xml file for store.war includes the following:

<filter>
  <filter-name>ADCDataInsertFilter</filter-name>
  <filter-class>
    atg.filter.ConditionalDelegatingFilter
  </filter-class>
  <init-param>
    <param-name>targetFilter</param-name>
    <param-value>
      atg.adc.filter.ADCDataInsertFilter
    </param-value>
  </init-param>
  <init-param>
    <param-name>mimeTypes</param-name>
    <param-value>text/html</param-value>
  </init-param>
</filter>
<filter-mapping>
  <filter-name>ADCDataInsertFilter</filter-name>
  <url-pattern>*.jsp</url-pattern>
</filter-mapping>

These settings specify that the atg.filter.ConditionalDelegatingFilter should run the atg.adc.filter.ADCDataInsertFilter if it is present. The ADCDataInsertFilter invokes the ADC processor pipeline. The filter is part of the ADC module, which is automatically included in the assembled EAR file when you specify the Store.Recommendations module.
